"That's the reason I come here, because it's always usually clean and quiet and parents are friendly," Martin said.

It really surprised her to hear a mother found a needle under a picnic table in the playground.

"I think it's odd," Martin said.

Natalie Marauly says she found it Thursday while in the park with her two kids.

"I look down at the ground, just kind of looking around and I noticed some type of needle on the ground under the bench," Marauly said. "It concerns me that things like that are found inside playgrounds fences where such young children could get ahold of them."

Marauly says she tried not to draw attention to it so her kids wouldn't be curious and then called police to come dispose of it.

"You don't want to be near that, it's a biohazard," Corporal Philip Mullen with Cape Coral Police said. "You don't know who that person was that used it."

Corporal Mullen says heroin use in on the rise.

"Our Vice, Intelligence and Narcotics Unit (VIN) has been hammering at it. We've arrested a bunch of dealers in the last few months," Corporal Mullen said.
